Best NASA Astronomy Pictures of the week: Double Galaxy Cluster, Comet ZTF and more
1/5 Double Star Cluster (Feb 20) - It is a 100-million-year-old globular star cluster located 160,000 light-years away in the constellation Dorado. What’s unusual about this star cluster is its size and shape is reminiscent of the other ancient star clusters in the Milky Way Galaxy. However, this double star cluster is not present in our galaxy and belongs in the Large Magellanic Cloud. (NASA/ESA/Hubble/Paul Goudfrooij(STScI))
2/5 Comet ZTF (Feb 21) - It is a mesmerizing picture of Comet ZTF streaking across the skies over Yosemite Falls located in the Sierra Nevada region of California. According to NASA, this comet was discovered by astronomers using the wide-field survey camera at the Zwicky Transient Facility in 2022 in March last year. (NASA/Tara Mostofi)
3/5 Rising Solar Activity (Feb 22) - This picture is a snapshot of the rising activity on the surface of the Sun. This image was captured two weeks ago in a single colour of light known as Hydrogen Alpha. Solar prominences can be observed hurling out from the surface while the Sun’s edges are brighter due to increased absorption of relatively cool solar gas. (NASA/Mehmet Ergun)
4/5 Spiral Galaxy Arp 78 (Feb 23) - A peculiar spiral galaxy called Arp 78 can be seen in this image. It is an enormous galaxy which spans nearly 200,000 light-years across and exists almost 100 million light-years away in the constellation Aries. Arp 78 is also known as NGC 772. Alongside Arp 78, another faint galaxy can be seen, which is NGC 770.  (NASA/Josep Drudis)
5/5 Headphone Nebula Jones-Emberson 1 (Feb 24) - A stellar nebula known as Jones-Emberson 1 also called as the Headphone Nebula owing to its peculiar headphone-like shape. The Headphone Nebula is located about 1600 light-years away from Earth in the constellation Lynx. (NASA/Serge Brunier/Jean-Francois Bax/David Vernet/ C2PU/OCA)

Can the universe be rewinded? Going into the past is impossible. However, scientists and researchers keep trying to go back in time. It is now being said that a new simulation shows how NASA's Nancy Grace Roman Space Telescope will turn back the cosmic clock, unveiling the evolving universe in ways that have never been possible before when it launches by May 2027.

"With its ability to rapidly image enormous swaths of space, Roman will help us understand how the universe transformed from a primordial sea of charged particles to the intricate network of vast cosmic structures we see today," a report by NASA stated. Notably, combining Roman's large view with Hubble Space Telescope's broader wavelength coverage and James Webb Space Telescope's more detailed observations will offer a more comprehensive view of the universe.

The simulation covers a two-square-degree patch of the sky, which is equivalent to about 10 times the apparent size of a full moon, containing over 5 million galaxies. It's based on a well-tested galaxy formation model that represents our current understanding of how the universe works.

Using an extremely efficient technique, the team can simulate tens of millions of galaxies in less than a day – something that could take years using conventional methods. When Roman launches and begins delivering real data, scientists can compare it to a range of such simulations, putting their models to the ultimate test. That will help unravel galaxy formation physics, dark matter – a mysterious substance observed only through its gravitational effects – and much more, the research organisation informed.

"Roman's panoramic view will help us see what the universe was like at different stages and fill in many gaps in our understanding," NASA said.

The Nancy Grace Roman Space Telescope is managed at NASA's Goddard Space Flight Center, with participation by NASA's Jet Propulsion Laboratory and Caltech/IPAC in Southern California, the Space Telescope Science Institute in Baltimore, and a science team comprising scientists from various research institutions.
